Answer:
3x+4 = 5
3x = 5-4
3x = 1
x = 1/3
Since the value of x is found, next step is to substitute it to the x for 6x+7
Value of 6x+7:
6(1/3)+7
6/3+7
2+7
9
Answer:
Option A. 56
Step-by-step explanation:
The question talks about chosing 5 presenters out of 8 presenter.
This can be achieved b using the following formula:
nCr = n! /r! (n–r)!
n = 8
r = 5
8C5 = 8! / 5! (8 – 5)!
8C5 = 8! / 5! 3!
8C5 = (8 x 7 x 6) / (3 x 2 x 1)
8C5 = 56
Therefore, there are 56 ways in which the teacher can chose the presenters.
